√49 = 7 so the square root of any number gives us the value, that can be squared to get the original number. here we have covered square numbers and their properties, you can refer to completing the square method which by following the link provided. to learn more about other ...
The right hand side is read as "3 squared", or "the square of 3", and this is equal to 9, as already shown. As another example, what is 4 squared? The answer can be found by simply multiplying 4 with itself, which shows that the square of 4 is equal to 16: 42=4×4=16...

The index that can quantify the behavior of the power system assessing the scale of power problems manifested in voltage, current, or frequency and that can be used for control system synthesis and evaluation. The next Sections describe the details of the introduced control problem and introduce ...
The law of large numbers applies to probability and statistics. It states that its mean gets closer to the average of the whole population as a sample size grows.

several statistical tests can be employed to assess the quality and randomness of a pseudorandom number generator. these tests evaluate properties such as uniformity, independence, and periodicity of the generated sequence. common statistical tests include the chi-squared test, the runs test, the ...
An imaginary number, when squared gives a negative result: This is normally impossible (try squaring a few numbers, remembering that multiplying negatives gives a positive, and see if you can get a negative result). But just imagine we have a number called i for imaginary that can do this:...
